CMT is the standard course from MTA (Market Technecians Association), which is based in NY, US. Their web address is www.mta.org. The course details and the contents are given at the site.
This course for technecians is also of three levels, with each level taken one after another . Exams are held twice a year once in Apr-May and the second time in Nov-Dec.
The first and second level is an online exam but in the third level one has to write a technical research paper which would be examined by existing CMT's.
For first level the charge is $500 for the registration and exam fees ...for the second and third level the exam fees is $400 for each. Additionally the upfront registration charge is $300.
So if one clears all CMT levels in first attempt then the total charge would be $1600.00
The UK course is STA Diploma and even Gabba has done that. However this one is much much inferior when compared to the US CMT.
